All:
So with some wailing and knashing of teeth, I was able to build the
IRKernel from source
and install that into my R environment.
So the tutorial uses r.ir - If I run a paragraph with that I get the
below stack trace.
If I run with just %ir it works (for some paragraphs). It also works
for some paragraphs with %spark.ir
Why the difference?
Running 0.9.0 built from source 2-3 days ago.
